  1. Characteristics of pathogens causing urinary tract infections in hospitals in North America : Results from the SENTRY Antimicrobial Surveillance Program, 1997.

    Article - En anglais

    Urinary tract infection (UTI) is common and involves pathogens with changing susceptibility patterns.

    The SENTRY Antimicrobial Surveillance Program evaluates international pathogen incidence patterns to detect and manage the emergence of resistant strains.

    We describe the antimicrobial resistance patterns among 1617 pathogens recovered from UTIs during the third-quarter of 1997 in North America (United States and Canada), as part of this worldwide program.

    The isolates were tested against more than 50 antimicrobial agents (20 reported) by reference broth microdilution methods, and selected isolates were characterized by pulsed-field gel electrophoresis (PFGE) and automated ribotyping.

    The five most frequently isolated species were Escherichia coli (48.6%), Enterococcus spp. (13.7%), Klebsiella spp. (12.0%), Pseudomonas aeruginosa (6.2%), and Enterobacter spp. or Proteus mirabilis (3.8% each).

    For each nation, imipenem and cefepime produced the widest spectrum of coverage among the bêta-lactams and amikacin was best among the aminoglycosides.

    For Gram-negative species, high resistance among bêta-lactam antimicrobial agents was noted especially for various penicillins against E. coli (37.9% to 42.8%) and for the cephalosporins tested against enterococci (99.4% and 100%). Approximately 7.0% ofenterococci in the USA were vancomycin-resistant (88% with Van A). (...)
